A VF52 turbo by iteself and alcohol injection should not be your very first two mods. Technically, no, you don't need to upgrade your exhaust with the VF52 turbo, but it would be very beneficial to do so. The stock downpipe is arguably the largest power-restrictor on the car. Start with one of those and couple it with some type of Stage 2 tune. After that, start collecting parts for a proper turbo upgrade (fuel pump, injectors, intercooler, intake, etc.) and install those at once and get a protune.

so, i had a tune already after installing an invidia high flow catted downpipe. i also got tein superstreet coilovers, which improved handling quite a lot over stock suspensions.

what's next?

a couple of 2nd hand stock 2011 sti tmic, air pump, and fuel pump are turning up for sale at good prices here where i'm from. are these bolt-ons on an 08wrx?

how much better (in terms of weight and stopping power) are big brake kits over stock brakes?

also, would there be any improvement if i only replace the rotors with larger ones (like this: http://www.speedlab.com.ph/index.php...t/view/233/209 ) but keep the calipers stock?

BBK's are alot of money and headache. You cant just slap them on and be good to go. Most of them mess with the brake bias and can often times mess up the stopping characteristics of the car. If you want better stopping power, get better pads, rotors, stainless steel brake lines and better fluid. It should handle more than enough for a daily driven car with occasional track duties.

hey, thanks for the reply! that confirms it then, no bbk's, but just pads, brake lines, and fluid.

but how about replacing just the rotors to 350mm's (like in the link above)? would it matter if i'm using stock calipers anyway?

I wouldn't.

Look into the HD Centrics. They have done real well on my car so far.

read this BOV FAQ Blow Off Valve FAQ: Read if you are thinking of buying one! - NASIOC
and this http://www.wrxtuners.com/forums/f51/bovs-newbs-32071/

but, in summary, "If you are wanting to be 100% sure you arent losing any power from a BOV, and you are running under about 22PSI, you are best off sticking with a stock unit."

Sorry, but, what is HD Centrics?


So, I guess, I'm really better off with just better pads, stock-sized rotors, stainless steel brake lines, better fluid, and a set of Neova ad08's? (excluding all possible weight-reduction mods)

Centric is a company that bought out DBA I believe. They have several types of rotors for each car.

you wouldn't, because... there'd be no benefit from it since your calipers are stock anyway?
